FHSA tax deduction: why it beats RRSP for your first home

The FHSA tax deduction works exactly like an RRSP contribution - it reduces your taxable income dollar for dollar. Put in $8,000, knock $8,000 off what gets taxed. At $75,000 in Ontario, that's roughly $2,500 back at tax time.

But here's what makes the FHSA different: when you pull money out for your first home, it's completely tax-free. No tax on the original contributions, no tax on any growth. An RRSP makes you pay tax when you withdraw - even under the Home Buyers' Plan.

How the deduction math works

Every FHSA contribution reduces your taxable income. Earn $75,000, contribute $5,000, and the CRA taxes you as if you earned $70,000. Your marginal tax rate determines how much you save.

In Ontario at $75,000, your marginal rate is about 31.5%. That $5,000 contribution saves you roughly $1,575 in taxes. TaxSplit.ca will show you the exact refund for your income and province.

The 2025 FHSA limit is $8,000 per year, with a $40,000 lifetime maximum. You get the deduction in the year you contribute - same as RRSP timing.

Why it beats RRSP for home buying

The Home Buyers' Plan lets you borrow up to $60,000 from your RRSP for a first home. You get 15 years to pay it back - but you have to pay it back. Miss a payment, and the CRA treats it as taxable income.

FHSA withdrawals for a qualifying home purchase aren't a loan. They're yours. No repayment schedule, no penalties if life gets complicated. The money comes out tax-free, and you're done.

Here's the same $40,000 saved in both accounts, assuming 5% annual growth over 8 years:

RRSP Home Buyers' Plan: You withdraw about $59,000 tax-free, but you owe the CRA $59,000 over 15 years. If you don't repay $3,933 annually, that amount gets added to your taxable income.

FHSA: You withdraw the full $59,000 tax-free with no repayment requirement. The account closes, and you move on.

The catch nobody mentions

You can't have both forever. Once you use either the FHSA or the Home Buyers' Plan, you can't contribute to the FHSA anymore - even if you never maxed it out.

And "first-time buyer" has specific rules. You can't have owned a home anywhere in the world during the four years before opening the FHSA. If you're married, neither can your spouse.

The FHSA also expires if you don't use it. You have until December 31st of the year you turn 71 to make a qualifying withdrawal. After that, it converts to an RRSP or RRIF, and future withdrawals get taxed.

When RRSP still makes sense

If you're buying soon - within two years - and you've already got $40,000 to save, the Home Buyers' Plan lets you borrow more. The FHSA caps at $40,000 lifetime; the HBP goes up to $60,000.

If you're not sure you'll buy a home, the RRSP keeps more options open. The FHSA only works for home purchases or retirement conversions.

But for most first-time buyers who know they want a house eventually: FHSA first, RRSP after.
